Problems solved by technology

Neither of them can effectively meet the driver's demand for predictable travel information.
[0010] In general, due to the poor visual characteristics of the road sections of the tunnel group and the lack of travel reminders and location reminders in the tunnel group in the current traffic safety design of the tunnel group, road traffic safety urgently needs a travel reminder system suitable for highway tunnel groups

Embodiment Construction

[0047] The technical solutions of the present invention will be described below in conjunction with the accompanying drawings and embodiments.

[0048] Such as Figure 1 to Figure 13 As shown, a road tunnel group travel reminder system according to the present invention includes a tunnel group perspective pattern signboard 1, a tunnel relative distance pattern signboard 2, a horizontal information signboard 3 and a vertical information signboard 4, through the tunnel group Perspective pattern signboard 1, tunnel relative distance pattern signboard 2, horizontal information signboard 3 and vertical information signboard 4 are combined to form the tunnel group forecast sign, tunnel entrance sign, tunnel entrance distance sign, and tunnel exit sign , Tunnel exit distance sign and tunnel group end sign, by laying out the position of tunnel group forecast sign, tunnel entrance indicator sign, tunnel entrance distance sign, tunnel exit indicator sign, tunnel exit distance sign and t...

Abstract

The invention relates to the technical field of road tunnel traffic safety, in particular to a road tunnel group travel reminder system, comprising a tunnel group perspective pattern sign, a tunnel relative distance pattern sign, a horizontal information sign and a vertical information sign. The position combination of group perspective pattern sign, tunnel relative distance pattern sign, horizontal information sign and vertical information sign constitutes tunnel group warning sign, tunnel entrance sign, tunnel entrance distance sign, tunnel exit sign, tunnel exit sign Distance signs and tunnel group end signs, through the arrangement of tunnel group warning signs, tunnel entrance signs, tunnel entrance distance signs, tunnel exit signs, tunnel exit distance signs and tunnel group end signs, constitute a combination of tunnel group front signs. , The road tunnel group travel reminder system is composed of the combination of signs before the tunnel exit, the combination of signs between tunnels and the combination of signs after the tunnel group.

Description

technical field [0001] The invention relates to the technical field of road tunnel traffic safety, in particular to a road tunnel group travel reminder system. Background technique [0002] With the rapid development of the social economy and the deepening of the traffic construction process, the construction of expressways is rapidly extending to the mountainous areas in the central and western regions. Most expressways pass through the mountains and the ratio of bridges and tunnels is high. The bridge-tunnel ratio of a large number of newly built and planned mountainous expressways is as high as 70%, and they often appear in the form of continuous tunnel groups and bridge-tunnel connections. The risk in terms of operational safety is much higher than that of other road sections. [0003] On the basis of the "black hole effect" and "white hole effect" visual characteristics of individual tunnels in the tunnel group road section, its unique visual problems are: due to the sh...
